SWIFTLETS HOME

This real image I like it very much. I like the swiftlet's sound, I like their flying ,and they know where to go,where to find food, where to stay and where to rest.They left home about 6.45am, and come back about 7.10pm till 7.50pm.(unless they had baby,then they came back about 2 to 4pm) About 12 hours to fly. My friends. Please build a real home for then to rest and not only build a bird's house for then to make their nests and lay their eggs. AFther that you can get more nests. SORRY MAYBE I AM WRONG. THANK YOU........
